Change in ovirt-engine[master]: core: Updating RNG devices on Cluster change

Arik Hadas has submitted this change and it was merged. Change subject: core: Updating RNG devices on Cluster change ...................................................................... core: Updating RNG devices on Cluster change urandom/random RNG device of cluster-aware VM-like entities needs to be updated when compatibility version of associated cluster is changed because we support 'random' RNG source for version 4.0 and lower and 'urandom' RNG source for 4.1 and higher. Custom compatibility version is honored allowing to run VM in 4.0 cluster with `urandom` device and VM in 4.1 cluster with `random`. However engine doesn't ensure that these devices will be present on hosts. Thus using custom compatibility level to get different RNG device is considered unsafe and should only be used to preview RNG generator behavior in non-critical VMs. This patch ensures that whenever cluster version is changed or cluster associated with VM or template is changes then RNG device of related entities are appropriately updated.
